Heart Sounds and Lung Sounds

In the ears and mind of a trained cardiologist, heart sounds can provide important information to help screen for certain diseases such as valvar lesions and many congenital defects. This application provides heart sounds and breath sounds or lung sounds in audio form that will enable users to evaluate different heart sounds in easy way. There are additional sounds for Pediatric congenital heart abnormality well precise in the app.

Heart sounds are brief, transient sounds produced by valve opening and closure; they are divided into systolic and diastolic sounds. Murmurs are produced by blood flow turbulence and are more prolonged than heart sounds; they may be systolic, diastolic, or continuous.

Heart sounds are produced from a specific cardiac event such as closure of a valve or tensing of a chordae tendineae. Many pathologic cardiac conditions can be diagnosed by auscultation of the heart sounds. Note that heart sounds are discrete, short audible events from a specific cause — different from a heart murmur. A murmur is due to turbulence of blood flow and can, at times, encompass all of systole or diastole.

The main normal heart sounds are the S1 and the S2 heart sound. The S3 can be normal, at times, but may be pathologic. A S4 heart sound is almost always pathologic. Heart sounds can be described by their intensity, pitch, location, quality and timing in the cardiac cycle. Learn more in the app.

Breath sounds can be either normal or abnormal. These sounds come from the lungs when you breathe in or out. These sounds can be heard using a stethoscope or simply when breathing. Abnormal breath sounds can indicate a lung problem, such as:
an obstruction
inflammation
an infection
fluid in the lungs
asthma
Listening to breath sounds is an important part of diagnosing many different medical conditions.
